IMPROVEMENT IN HYPODERMlC-SYRINGE BOTTLES.

Specification forming part of Letters Patent No. 195,947, dated October9, 1877; application filed August 1, 1877.

To all whom it may concern:

Be it known that I, EDWARD PFARRE, of Brooklyn, in the county of Kingsand State of New York, have invented an Improvement in Bottles forHypodermic Syringes, of which the following is a specification:

Great inconvenience is experienced in filling a hypodermic syringe fromthe ordinary straight bottle, because it usually has a narrow neck, andis liable to upset. The narrow neck prevents the insertion of the end ofthe syringe, and as the liquid is drawn into the syringe its levelbecomes lower in the bottle; and if the tubular end to the syringe isused, or the syringe is screwed upon the bottle itself, a partial vacuumis liable to be formed, so that the piston returns partially whenreleased, and often some of the fluid re-enters the bottle. Theliability to spill the contents of the bottle is increased by the factthat the bottle has to be removed from the case and stood upright.

All these difficulties are overcome by my improvement, which consists ina bottle with a neck at one side, instead of the end, and a case adaptedto hold the same in a horizontal position, with the neck and stopperturned aside, so that the case will close easily, or with the neckturned upwardly, so that the stopper can be removed and the end of thesyringe inserted to the surface or bottom of the liquid, in order thatthe same may be drawn easily into the syringe without the risk ofspilling the liquid or of inaccuracy in the measurement of the contentsof the syringe.

In the drawing, Figure 1 is a plan of the case, syringe, and bottle.Fig. 2 is a crosssection of the case and bottle at the line 00 w.

The syringe a and injecting-tubes b are of usual character, and the case0 is of the character generally employed, only it is adapted to thepeculiar shape of the bottle.

The bottle 6 is of a length to set within the case 0, and both ends areclosed. There is, however, a neck, '5, at one side of the bottle, of asize that will admit the end of the syringe to be inserted to the bottomof the liquid in the bottle.

The stopper f is of india-rubber or other suitable material; and whenthe bottle is not in use the neck '2 and stopper f are to be turned downinto the position shown by dotted lines in Figs. 1 and 2, so that thecase can be closed; but when in use the neck is to be brought upwardly.The bottle is preferably cylindrical; but it might be prismatic.

Within the case 0 is the stop-block 0, covered with velvet or othersuitable material, so as to produce the requisite friction against thesides of the bottle, to hold the same in either position to which it maybe turned. This block is shown by dotted lines in Fig. 2.

I claim as my invention The bottle for hypodermic syringes of a lengthto fit into the syringe-case, and having a neck projecting at one sideto receive the stopper, said neck being of a size to allow ot' theinsertion of the end of the syringe, substantially as set forth.
